JOURNAL-BEARING.

SPECIFICATION forming part of Letters Patent No. 447,492, dated March 3,1891.

Application filed December 22, 1890. Serial No. 375,465. (No model.)

To all whom it may concern.-

Be it known that I, MELVIN NEWTON Lov- ELL, a citizen of the UnitedStates, residing at Erie, in the county of Erie and State ofPennsylvania, have invented certain new and useful Improvements inJournal-Bearings for ClOtlleS-VIIII gers and other Roller-Machines; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilledin theart to which it appertains to make and use the same.

This invention relates to journal-bearings which are applicable toroller-expressing machines, such as clothes-wringers, for example; andit consists in certain improvements in the construction of the same, aswill be hereinafter fully set forth, and pointed out in the claims.

My device is illustrated in the accompanying drawings, as follows:

Figure 1 is a vertical section of a fragment of aclothes-wringingmachine, theline of section being along the axis of theexpressingrolls and shows my improved journal-bearings applied thereto.Fig. 2 is a vertical section, in the same direction as in Fig. 1, of apart of one of the journal-boxes. Fig. 3 is a side elevation view of thepart shown in Fig. 2.

Letters of reference indicate parts as follows:

A marks the upright post of a clotheswringer; B, thetop cross-piece; OO, the springbars; 0, the tension-screw; D D,the rolls; E E, the shaftsof the rolls; F, thejournal-boxes.

The above-named parts, with the exception of the journal-boxes, are madeas commonly, or may be of any constructiondesired,and form no part of myinvention.

The construction of the journal-box is as follows: A plain cylindricalcase G is formed of a section of tubing finished smooth and even on itsinner wall and with such finish on its outer walls as may be desired.Within this case in the annular space between the shaft and the innerwall of the case are as many rollers II as will fill that spaceproperly.

The case G is then embraced by a clamp F F, which is adapted to be heldby the framework of the machine. The outer form of the clamp, which mayalso be said to be the body of the journal-box, may be varied to suitthe surrounding parts with which it is used. As

the boxes from moving longitudinally on the shafts and at the same timeallows them to move vertically when necessary. It the posts A wereprovided with tongues in place of the grooves a, then the body of theboxes F should be provided with grooves in place of the tongues f Anyother change of form of the exterior of the body of the boxes which maybe necessary or desirable to adapt the same to the frame-work of themachine may be given them without departing from my invention.

The essential features of the construction of the body or clamp F F arethat it be in two parts, which are secured together by bolts, screws,orrivets, and that the said parts extend over and embrace the ends ofthe case or barrel G and hold the rollers H in place within the barrel.To this end the clamp or body is made of two parts F F, each of whichhas a flange F which is annular in form and of such size as to cover theends of the barrel or cylinder G, and on the inner side of these flangesthere is an annular rib f which enters the ends of the barrel G andapproaches closely to the ends of the rollers H. The upper part of theclamp-sections arch over the barrel and form a coping therefor, and thenterminate in a head or seat for the spring-bars O to rest on whendesired. The two parts F F are shown secured together by the rivets orbolts f.

lVhile my improved journal-box is shown as applied to aroller-expressing machine, I do not intend to be limited to sucha use.

I am aware that roller-bearings have been made heretofore in which therewas a cylinder or barrel containing the rollers with caps over the endsof the cylinder to hold the rollers in place, and I do not intend to beunderstood as claiming that feature broadly. In the former constructionsjust referred to the caps were not connected with a clamp, as are theflanges F of my construction, and the boxes so formed were not adaptedto the purposes for which the boxes I show are intended, as expressed inthe foregoing description.

\Vhat I claim as new is- 1. The combination, for the purposes named, ofthe cylinder G, the rollers l-I, contained within said cylinder, and thebox F, formed of the two parts 1 F, bolted together as shown, and thusforming a clamp, and having; flanges F which embrace the ends of saidcylinder and retain the rollers II therein.

2. The combination, for the purposes named, of the cylinder G, therollers II, contained within said cylinder, and the box F, formed
